Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy project power supply, and in particular to a hydrogen fuel cell power supply system suitable for water conservancy projects. Background Art

[0002] As an emerging clean energy, hydrogen energy is gradually becoming an important pillar of global energy transformation and sustainable development with its multiple advantages such as environmental friendliness, high energy efficiency, strong renewability, diversified application scenarios and cost reduction potential, showing great potential in energy transformation and green development.

[0003] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis, providing hydrogen and oxygen to the anode and cathode respectively. When hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through an external load. Fuel cells do not pollute the environment, and they use electrochemical reactions instead of combustion (such as gasoline and diesel). Fuel cells can only produce water and heat, without harmful emissions, and have low labor maintenance costs and strong temperature adaptability.

[0004] In the field of water conservancy projects, the requirements for electricity consumption are high, and sudden power outages will cause losses to people's personal safety and property. Therefore, the field of water conservancy projects is usually equipped with backup power supplies. At present, the power source of the mobile power supply vehicle system in the market is mainly diesel generators, and the fuel of diesel generators is diesel, and they are equipped with oil storage tanks. From the perspective of energy saving and environmental protection, it is contrary to the country's green and low-carbon strategy; and the noise of the general engine unit when working is about 110dB. In order to reduce noise, the power supply vehicle system in the market has added mufflers, anti-noise devices, sound-absorbing cotton on the side panels of the car box, or sealing strips on the car box doors and windows. The working structure is complex; and the working efficiency of the existing diesel generator system is relatively low, and the energy consumption of electricity is large; finally, most of the existing mobile diesel generator operation control systems use mechanical or electrical switches to operate the corresponding functions, and it is impossible or inconvenient to control the working technical parameters in the system in real time.

[0005] Based on the above problems, water conservancy projects urgently need a mobile power supply system for small and medium-sized sluices to better and more conveniently power these sluices. To this end, a hydrogen fuel cell power supply system suitable for water conservancy projects is proposed. Summary of the invention

[0018] After the hydrogen fuel cell module is started, when it reaches its rated output power, the power conversion module cuts off the output of the lithium battery energy storage module, and the hydrogen fuel cell module supplies power to the load. At the same time, the hydrogen fuel cell module reversely charges the lithium battery energy storage module through the power conversion module. The power conversion module collects temperature, humidity, current, and voltage data of each device in each system. After the data is collected, it is fed back to the automatic control module to prepare for starting the cooling module.
